NBC wants to make sure viewers can watch President Obama’s farewell speech Tuesday without having to miss — or DVR — the midseason return of its breakout drama This Is Us.


CBS, meanwhile, will re-run the Season 9 finale of The Big Bang Theory in place of Bull after the speech.
NBC said today that This Is Us‘ “The Right Thing to Do” episode – the series’ first original since the December 6 Christmas episode – will air at 10 PM Eastern, 9 PM Central, and twice back-to-back Pacific starting at 9 PM.
An encore airing of new game show The Wall will be joined in progress after the president’s address, which is expected to run 40 minutes, and the Chicago Fire episode originally scheduled for 10 PM January 10 will air a week later, on January 17.
